Question 1 of 5
Gerald can bake 3 dozen cookies in 30 minutes. How long will it take him to bake 12 dozen cookies?
Correct Answer: B
Rationale: If Gerald can bake 3 dozen cookies in 30 minutes, then he can bake 1 dozen cookies in 10 minutes (30 minutes / 3 = 10 minutes). To bake 12 dozen cookies, it would take him 120 minutes (12 dozen x 10 minutes = 120 minutes), which is equivalent to 1 hour and 40 minutes. Choice A (90 minutes) is incorrect because it does not account for the correct proportion of cookies baked. Choice C (2 hours) and Choice D (4 hours) are incorrect as they overestimate the time required based on the given information.
Question 2 of 5
What would be the total cost to buy 5 bars of soap if one bar of soap costs $0.96?
Correct Answer: D
Rationale: To find the total cost of purchasing 5 bars of soap, multiply the cost of one bar of soap by the number of bars. If one bar costs $0.96, then 5 bars would cost $0.96 x 5 = $4.80. Therefore, the correct answer is $4.80. Option A, $3.30, is incorrect as it does not result from the correct multiplication. Option B, $3.80, is also incorrect as it does not reflect the total cost of 5 bars. Option C, $4.30, is incorrect as it does not represent the accurate total cost of purchasing 5 bars of soap.

Question 4 of 5
Eighty percent of the class passed with a 75 or higher. If that percentage equals 24 students, how many students were in the whole class?
Correct Answer: C
Rationale: If 80% of the class passed with a 75 or higher, and that equals 24 students, you can set up a proportion to find the total number of students in the class. Since 80% is equal to 24 students, 100% (the whole class) would be equal to (24/80) x 100 = 30 students. Therefore, the total number of students in the whole class is 30 / 80 x 100 = 36. Choice A (18) is incorrect as it does not match the calculation based on the information given. Choice B (30) is incorrect because it represents the intermediate calculation but not the total number of students in the class. Choice D (60) is incorrect as it is double the correct answer and does not align with the given information.
Question 5 of 5
If a party planner assumes 2 bottles of sparkling water per 5 guests, how many bottles must she purchase for a party of 145 guests?
Correct Answer: D
Rationale: If the party planner assumes 2 bottles of sparkling water per 5 guests, for a party of 145 guests, she would need ((2/5) x 145) bottles of sparkling water. This calculation results in 58 bottles. Therefore, she must purchase 58 bottles for the party of 145 guests. Choices A, B, and C are incorrect as they do not reflect the correct calculation based on the given assumption.
